Ok, my website has 3 columns, the rightside is a table of links, the center is the content, and the left is more links. Where do I put my SSI(<!--#include file="yourfilename.txt" -->)in the HTML documents? I want the SSI to have everything except the content.

You could do something like this:

<table>
<tr>
<td><!--#include file="leftmenu.txt" --></td>
<td>content</td>
<td><!--#include file="rightmenu.txt" --></td>
</tr>
</table>

Ok i'll try that thanks lissa!
